The main goal of independence was to establish a non-communal Bangladesh to be freed from hunger and poverty, President Mohammed Shahabuddin said on Thursday.
But the anti-independence group obstructed the achievement of that goal by assassinating Bangabandhu and his family in 1975.
The president made the remarks while a delegation led by president of Ghatak Dalal Nirmul Committee Shahriar Kabir paid a courtesy call on him at Bangabhaban on Thursday.

During the meeting, the delegation of Ghatak Dalal Nirmul Committee invited the President to attend its National Conference to be held on May 3.
